BACKGROUND Field of the Invention

Description of Related Art

It is now generally accepted that ultraviolet (UV) radiation can be a serious health hazard. Even a limited exposure to solar radiation can cause short- and long-term skin damage, such as erythema, burns, wrinkles, lentigo (“liver spots”), skin cancers, keratotic lesions, and other cellular changes. There is a greater risk for developing such conditions for those who send prolonged time in the sun, such as for their occupation or during recreation.

UV radiation is just one portion of the electromagnetic spectrum with wavelengths from about 100 nm and about 400 nm, and is further divided into three subregions. UV-A radiation, from about 320 nm to about 400 nm, has the longest wavelength within the UV spectrum, and consequently is the least energetic. While UV-A rays can induce skin tanning, they are liable to induce adverse changes as well, especially in the case of sensitive skin or of skin which is continually exposed to solar radiation. In particular UV-A rays cause a loss of skin elasticity and the appearance of wrinkles, leading to premature skin aging. UV-B rays have shorter wavelengths, from about 290 nm to about 320 nm, and their higher energy can cause erythema and skin burns which may be harmful. The third subgroup, UV-C has the shortest wavelengths, from about 200 nm to about 290 nm, and the highest energy. The Earth's ozone layer effectively filters much UV-C radiation from reaching the ground. Nonetheless, UV-C rays can be generated from tanning bed devices.

In addition to harming the skin, UV radiation can injure the hair, resulting in color changes (especially for color-treated hair), embrittlement, and a loss in aesthetics (e.g., shine, manageability).

UV radiation damage is not limited to the skin and hair, as inanimate objects exposed to solar radiation can experience changes related to color, hardness, and structural integrity, which can contribute to aesthetical and functional deterioration. Thus, there is the very real and demanding need for compositions that protect the skin, hair, and objects from UV rays, especially UV-A and UV-B radiation. Of special interest are compositions that provide broad UV-spectrum protection from both UV-A and UV-B radiation.

Broadly speaking, para-aminobenzoic acid (PABA) exhibits a common trait shared with many UV absorbers/filters. The molecule possesses both electron withdrawing and electron accepting groups, providing resonance delocalization that coincides with the absorbed energy of UV radiation:

However, PABA is a highly polar molecule, making it water soluble, and giving it low persistence, meaning that it is not highly retained on the skin after swimming or perspiring. In addition, due to extensive intermolecular bonding, PABA exists as a solid, which may further complicate its formulation. Thus, there exists the need to improve the persistence of UV absorbers, especially those that are water-soluble, and to provide formulation flexibility.

UV absorbers may exhibit photolability, in which the absorbed energy causes photodegradation and/or photoreactivity, and thus reduce its efficacy. Such photolability may result from irreversible isomerisms (i.e., keto-enol tautomerism and cis-trans isomerism), photocleavage, and/or photoaddition, and may be formulation sensitive, (e.g., blends of avobenzone and octinoxate). Examples of photolabile UV absorber include, without limitation: avobenzone, PABA derivatives, cinnamates, and dibenzoyl methane derivatives, all of which degrades over time, and reduce UV protection. Hence, there exists a need to stabilize UV absorbers from photodegradative effects.

Additionally, there exists the need to enhance the efficacy of UV absorbers without increasing their content in the formula, since a maximum addition level frequently is regulated. This efficacy need is especially important for avobenzone, a highly effective UV-A absorber. Avobenzone is subject to keto-enol isomerization due to formulation dependencies (e.g., solvent, other UV absorbers):

The enol tautomer (left) has its maximum absorbance at 357 nm, which identifies it as a UV-A absorber. Unfortunately, avobenzone is subject to bimolecular reactions (viz, via cleavage mechanisms) that alter the molecule's structure and decrease its effectiveness as an UV absorber. Hence, an effective method is needed for stabilizing labile chromophores like avobenzone in order to enhance their efficacy without increasing their addition level.

Methods for stabilizing chromophores, and in particular UV absorbers, are known in the prior art. For example, Japanese patent 1971/26,860 describes UV stabilizers having amino, hydroxyl, or isocyanate groups attached to crosslinked polymers, being crosslinked glycidyl methacrylate-divinylbenzene copolymers or crosslinked styrene-maleic anhydride-divinylbenzene copolymers.

U.S. Pat. No. 4,868,246 teaches polymer chemistries having UV absorbers bonded to recurring units:

in the polymer backbone, on grafted side chains, as pendant units, or as combinations thereof. The group N-G is the residue of a primary amino or hydrazido substituted stabilizer group selected from (a) 2-hydroxybenzophenones, (b) 2-(2-hydroxyphenyl)-2H-benzotriazoles, (c) aryl salicylates, or (d) oxalic acid amides. The polymeric stabilizers are directed for use in other polymeric systems which are normally subject to actinic light degradation, for example polypropylene. No mention is made of their use in personal care compositions.

A similar approach is taught in U.S. Pat. No. 4,857,596 for thermally stabilizing antioxidants.

Polymer-bound light stabilizers are disclosed in U.S. Pat. No. 4,975,494 that are prepared from a preformed polymer having two different types of reactive groups and a light stabilizer having hydrazido functionality.

U.S. Pat. No. 6,569,531 teaches additive-containing resins having a bi- or multifunctional additive linking a polyester resin with an additive, such as a UV absorber.

U.S. Pat. No. 7,648,697 teaches compounds derived from polyanhydride resins with film-forming, UV-absorbing, and photostabilizing properties.

Japanese patent 1985/84,378 provides 2-hydroxy-4-(2-hydroxyethoxy)benzophenone reacted with maleic anhydride-grafted polyethylene to form a polyethylene-bound 2-hydroxybenzophonone semi-ester.

Two radiation-absorbing polymer chemistries are taught in U.S. Pat. No. 6,255,405. The '405 patent is directed toward radiation-absorbing compositions and coatings, particular for “forming a bottom anti-reflective coating upon producing an integrated circuit.” The polymeric compositions comprise two recurring units, the first having the formula:

wherein R_(a) and R_(b) may be the same or different and represent hydrogen, an alkyl group or other organic groups, Ar represents an organic chromophore, and n represents 0 or an integer of 1 or more; and the second recurring unit having the formula:

wherein R_(c) and R_(d) may be the same or different and each represents hydrogen, an alkyl group, a carboxyl group, or other organic groups, and Z represents hydrogen, a substituted or non-substituted alkoxyl group, a substituted or non-substituted alkyl group, a halogen atom, —CN, an alkylcarbonyloxy group, an imide group, a substituted or non-substituted carbamoyl group, a substituted or non-substituted oxycarbonyl group, or a substituted or non-substituted phenyl group.

U.S. Pat. No. 6,492,455 discloses compositions comprising the reaction product of a C₆+ alpha olefin/maleic anhydride copolymer with a polyfunctionalized secondary or tertiary amine. The resulting copolymer is an alternating copolymer of an olefinic monomer and a maleic anhydride with a polyfunctionalized secondary or tertiary amine. Uses includes hair spray and water-proof sunscreen compositions

U.S. Pat. No. 7,361,710 describes compositions comprising the reaction of (a) an unsaturated vegetable oil and an enophile or dienophile having acid, ester, or anhydride functionality and (b) a functional vinyl monomer. For example, soybean oil is reacted with maleic anhydride, to yield a maleated vegetable oil:

The maleated oil is reacted with hydroxyethyl methacrylate, 2-(tert-butylamino)ethyl methacrylate, or glycidyl methacrylate.

Another maleated oil is described in U.S. Pat. No. 3,428,589, which is directed to polycarboxylic acid anhydride resins of high viscosity, and for such resins of voltage capabilities. This invention discloses the heating (1) of a dry oil, a modified drying oil, or a mixture thereof, and (2) and alpha, beta-ethylenically unsaturated dicarboxylic acid anhydride, which is heated until a polycarboxylic acid anhydride resin product (i.e., an adduct) with a desirably high viscosity is obtained. The polycarboxylic acid anhydride resin is then reacted with an organic aromatic primary or secondary amine, as represented in the following reaction:

wherein R′ represented the drying oil portion of the adduct, and R″ is hydrogen or alkyl. The '589 patent specifies that the organic aromatic primary or secondary amine has from 1 to 20 carbon atoms, preferably from 1 to 10 carbon atoms. The '589 patent discloses compositions for electrocoating baths, compositions with high throwing power, and of excellent intermediate voltage capacity.

Additional disclosure related to anhydride-functionalized vegetable oils is provided by Aydin, S., et al., Prog Org Coat, 51, 273-279, 2004; and by Guner, F. S., et al., Prog Polym Sci, 31, 633-670, 2006, both of which are incorporated in their entirety by reference. While these works describe methods to graft anhydride functional groups onto vegetable oils, they do not teach subsequent grafting of UV absorbers onto the anhydride moiety.

Functionalized poly(alpha olefin-maleic anhydride) polymers are the subject of application WO 2007/096400A1. This functionalized copolymer has the structure:

wherein X is −O— or —NH—, and —X—R₂— is a functional radical selected from a group that includes natural molecules that are UV absorbers, such as tannins, flavonoids, thymol, caffeic acid esters, and vitamin E.

UV absorbers bound to polymers in personal care compositions are taught in US 2010/0189661, the contents of which are incorporated in their entirety by reference.

Despite advances in UV-absorbers, there remains a commercial demand for UV-absorbing polymers with enhanced performance.

The first repeating unit of UV-absorbing polymers described herein may be a residue of an anhydride monomer that may be functionalized by one or more UV-absorbing compound(s). Particularly, the anhydride monomer prior to functionalization may be selected from the group consisting of maleic anhydride, methyl maleic anhydride, dimethyl maleic anhydride, itaconic anhydride, citraconic anhydride, chloromaleic anhydride, bromomaleic anhydride, dichloromaleic anhydride, dibromomaleic anhydride, phenylmaleic anhydride, and combinations thereof. The functionalization of anhydride monomers by one or more UV-absorbing compound(s) results in formation of amic acid, amic acid salt, ester acid, ester acid salt, diester, diamide, ester amide, and/or imide moieties.

In one embodiment, the anhydride monomers may be functionalized by one or more UV-absorbing compound(s) followed by polymerization to yield UV-absorbing polymers. In an alternative embodiment, a polymer having one or more reactive anhydride, ester acid, amic acid, ester acid salt, amic acid salt, diester, diamide, ester amide, and/or imide moieties on the polymer backbone may be functionalized by post-polymerization modification reaction(s) to yield UV-absorbing polymers. The resulting UV-absorbing polymers include homopolymers, copolymers, terpolymers, and higher homologues.

The polymer backbone may be a homopolymer of an anhydride monomer, such as, poly(maleic anhydride), poly(dimethyl maleic anhydride), poly(methyl maleic anhydride), and poly(citaconic anhydride).

Alternatively, the polymer backbone may be provided by a copolymer. One non-limiting, exemplary member of this copolymer class may be poly(styrene-co-maleic anhydride), which are a general class of alternating copolymers of styrene and maleic anhydride, or the non-equimolar copolymers containing less than about 50 mole percent of the anhydride monomer. This copolymer may be defined by its generic chemical structure:

wherein the subscripts y and z represent the molar ratios of the repeating units. The styrene constituent in poly(styrene-co-maleic anhydride) may be replaced in whole or in part by other vinylaromatic monomers such as alpha-methylstyrene, nuclear methylstyrenes, ethylstyrene, iso-propylstyrene, tert-butylstyrene, chlorostyrenes, dichlorostyrenes, bromostyrenes, dibromostyrenes, vinylnaphthalene and the like. Similarly, the maleic anhydride can be replaced in whole or in part by another alpha, beta-unsaturated cyclic dicarboxylic acid anhydride such as citraconic, chloromaleic, itaconic, bromomaleic, dichloromaleic, dibromomaleic, phenylmaleic, and the like. Particularly, the alpha, beta-unsaturated cyclic anhydride may be maleic anhydride. Suitable poly(styrene-co-maleic anhydride) copolymers may be prepared by any of the several methods available for the preparation of styrene-maleic anhydride copolymers or they may be purchased commercially. Non-equimolar copolymers may be prepared by solution polymerization directly from the respective monomers by the incremental addition of the reactive monomer as taught by U.S. Pat. No. 2,971,939, by a continuous recycle polymerization process such as described in U.S. Pat. Nos. 2,769,804 and 2,989,517, by the suspension polymerization process described in U.S. Pat. No. 3,509,110, or by numerous known variations.

A second non-limiting example of a copolymer is a poly(alkyl vinyl ether-co-anhydride), such as poly(methyl vinyl ether-co-maleic anhydride):

wherein the subscripts y and z represent the molar ratios of the repeating units.

Particularly, this copolymer may be predominantly alternating poly(methyl vinyl ether-co-maleic anhydride).

Poly(methyl vinyl ether-co-maleic anhydride) is offered for commercial sale as Gantrez™ AN by International Specialty Products (Wayne, N.J.).

Regardless of the synthesis approach, the imide forms can be created from the amic acid form through the application of heat, the use of a reaction catalyst, or the use of a reaction initiator, or combinations thereof.

No. 3,988,433. Carrier materials for biphasic dentifrice formulations are disclosed in U.S. Pat. Nos. 5,213,790; 5,145,666; 5,281,410; 4,849,213; and 4,528,180. Mouthwash, rinse or mouth spray carrier materials typically include water, flavoring and sweetening agents, etc., as disclosed in, e.g., U.S. Pat. No. 3,988,433. Lozenge carrier materials typically include a candy base; chewing gum carrier materials include a gum base, flavoring and sweetening agents, as in, e.g., U.S. Pat. No. 4,083,955. Sachet carrier materials typically include a sachet bag, flavoring and sweetening agents. For sub-gingival gels used for delivery of actives into the periodontal pockets or around the periodontal pockets, a “sub-gingival gel carrier” is chosen as disclosed in, e.g., U.S. Pat. Nos. 5,198,220 and 5,242,910. The selection of a carrier will depend on secondary considerations like taste, cost, and shelf stability, and other factors.

Oral care compositions may comprise one or more dental abrasives. Dental abrasives useful in the compositions include many different materials. The material selected must be one which is compatible within the composition of interest and does not excessively abrade dentin.

Non-limiting examples of suitable abrasives include: silicas including gels and precipitates, insoluble sodium polymetaphosphate, hydrated alumina, calcium carbonate, dicalcium orthophosphate dihydrate, calcium pyrophosphate, tricalcium phosphate, calcium polymetaphosphate, resinous abrasive materials such as particulate condensation products of urea and formaldehyde, and blends thereof.

Another class of abrasives is the particulate thermo-setting polymerized resins as described in U.S. Pat. No. 3,070,510.

Non-limiting examples of suitable resins include: melamines, phenolics, ureas, melamine-ureas, melamine-formaldehydes, urea-formaldehyde, melamine-urea-formaldehydes, cross-linked epoxides, cross-linked polyesters, and blends thereof.

Silica dental abrasives of various types may be employed because of their unique benefits of exceptional dental cleaning and polishing performance without unduly abrading tooth enamel or dentine. The silica abrasive polishing materials herein, as well as other abrasives, generally have an average particle size ranging from about 0.1 to about 30 microns, and particularly from about 5 to about 15 microns. The abrasive can be precipitated silica or silica gels such as the silica xerogels described in U.S. Pat. No. 3,538,230, and U.S. Pat. No. 3,862,307.

Non-limiting examples of suitable silica abrasives include: silica xerogels marketed under the trade name “Syloid” by the W.R. Grace & Company, Davison Chemical Division and precipitated silica materials such as those marketed by the J.M. Huber Corporation under the trade name, Zeodent®, particularly the silicas carrying the designation Zeodent® 119, Zeodent® 118, Zeodent® 109 and Zeodent® 129. The types of silica dental abrasives useful in the toothpastes of the invention are described in more detail in U.S. Pat. Nos. 4,340,583; 5,603,920; 5,589,160; 5,658,553; 5,651,958; and 6,740,311. Each of these disclosures is hereby incorporated in its entirety by reference.

Mixtures of abrasives can be used such as mixtures of the various grades of Zeodent® silica abrasives listed above.

The total amount of abrasive(s) in the oral care compositions typically range from about 6% to about 70% by weight; toothpastes may contain from about 10% to about 50% of abrasives by weight of the composition. Dental solution, mouth spray, mouthwash and non-abrasive gel compositions typically contain little or no abrasives.

Oral care compositions may comprise polymeric mineral surface active agent(s) (PMSAs). PMSAs include any agent which will have a strong affinity for the tooth surface, deposit a polymer layer or coating on the tooth surface and produce the desired surface modification effects. The “mineral” descriptor is intended to convey that the surface activity or substantivity of the polymer is toward mineral surfaces such as calcium phosphate minerals or teeth.

Non-limiting examples of suitable PMSAs include: polyelectrolytes such as condensed phosphorylated polymers; polyphosphonates; copolymers of phosphate- or phosphonate-containing monomers or polymers with other monomers such as ethylenically unsaturated monomers and amino acids or with other polymers such as proteins, polypeptides, polysaccharides, poly(acrylate), poly(acrylamide), poly(methacrylate), poly(ethacrylate), poly(hydroxyalkylmethacrylate), poly(vinyl alcohol), poly(maleic anhydride), poly(maleate) poly(amide), poly(ethylene amine), poly(ethylene glycol), poly(propylene glycol), poly(vinyl acetate), poly(vinyl benzyl chloride), polycarboxylates, carboxy-substituted polymers, and blends thereof. Also suitable as polymeric mineral surface active agents are the carboxy-substituted alcohol polymers described in U.S. Pat. Nos. 5,292,501; 5,213,789, 5,093,170; 5,009,882; and 4,939,284; and the diphosphonate-derivatized polymers in U.S. Pat. No. 5,011,913; the synthetic anionic polymers including polyacrylates and copolymers of maleic anhydride or acid and methyl vinyl ether (e.g., Gantrez®), as described, for example, in U.S. Pat. No. 4,627,977. Another example of a polymeric mineral surface active agent is a diphosphonate modified polyacrylic acid.

Polymers with activity must have sufficient surface binding propensity to desorb pellicle proteins and remain affixed to enamel surfaces. For tooth surfaces, polymers with end or side chain phosphate or phosphonate functions may be used, although other polymers with mineral binding activity may prove effective depending upon adsorption affinity.

PMSAs are useful in the compositions because of their stain prevention benefit. It is believed the PMSAs provide a stain prevention benefit because of their reactivity or substantivity to mineral surfaces, resulting in desorption of portions of undesirable adsorbed pellicle proteins, in particular those associated with binding color bodies that stain teeth, calculus development and attraction of undesirable microbial species. The retention of these PMSAs on teeth can also prevent stains from accruing due to disruption of binding sites of color bodies on tooth surfaces.

The ability of PMSA to bind stain promoting ingredients of oral care products such as stannous ions and cationic antimicrobials is also believed to be helpful. The PMSA will also provide tooth surface conditioning effects which produce desirable effects on surface thermodynamic properties and surface film properties, which impart improved clean feel aesthetics both during and most importantly, following rinsing or brushing. Many of these polymeric agents are also known or expected to provide tartar control benefits when applied in oral compositions, hence providing improvement in both the appearance of teeth and their tactile impression to consumers. The desired surface effects may include: 1) creating a hydrophilic tooth surface immediately after treatment; and 2) maintaining surface conditioning effects and control of pellicle film for extended periods following product use, including post brushing or rinsing and throughout more extended periods. The effect of creating an increased hydrophilic surface can be measured in terms of a relative decrease in water contact angles. The hydrophilic surface, importantly, is maintained on the tooth surface for an extended period after using the product.

Oral care compositions may comprise additional anticalculus agent(s), such as a pyrophosphate salt as a source of pyrophosphate ion.

Non-limiting examples of suitable pyrophosphate salts include: dialkali metal pyrophosphate salts, tetraalkali metal pyrophosphate salts, and mixtures thereof. Particularly, disodium dihydrogen pyrophosphate (Na₂H₂P₂O₇), tetrasodium pyrophosphate (Na₄P₂O₇), and tetrapotassium pyrophosphate (K₄P₂O₇) in their unhydrated as well as hydrated forms may find utility.

In compositions of the invention, the pyrophosphate salt may be present in one of three ways: predominately dissolved, predominately undissolved, or a mixture of dissolved and undissolved pyrophosphate.

Compositions comprising predominately dissolved pyrophosphate refer to compositions where at least one pyrophosphate ion source is in an amount sufficient to provide at least about 1.0% free pyrophosphate ions. The amount of free pyrophosphate ions may be from about 1% to about 15%, particularly from about 1.5% to about 10%, and more particularly from about 2% to about 6%. Free pyrophosphate ions may be present in a variety of protonated states depending on the pH of the composition.

Compositions comprising predominately undissolved pyrophosphate refer to compositions containing no more than about 20% of the total pyrophosphate salt dissolved in the composition, particularly less than about 10% of the total pyrophosphate dissolved in the composition. Tetrasodium pyrophosphate salt may be one such pyrophosphate salt in these compositions. Tetrasodium pyrophosphate may be the anhydrous salt form or the decahydrate form, or any other species stable in solid form in the oral care compositions. The salt is in its solid particle form, which may be its crystalline and/or amorphous state, with the particle size of the salt being small enough to be aesthetically acceptable and readily soluble during use. The amount of pyrophosphate salt useful in making these compositions is any tartar control effective amount, generally from about 1.5% to about 15%, particularly from about 2% to about 10%, and more particularly from about 3% to about 8% by weight of the oral care composition.

The pyrophosphate salts are described in more detail in Kirk-Othmer Encyclopedia of Chemical Technology, third edition, volume 17, Wiley-Interscience Publishers (1982).

Oral care compositions may comprise peroxide compounds.

Non-limiting examples of suitable peroxide compounds include: hydrogen peroxide and organic peroxides including urea peroxide, carbamide peroxide, glyceryl peroxide, benzoyl peroxide, derivatives thereof, and blends thereof.

Typically, the peroxide compound can be employed in amounts so that at least about 1% by weight of the composition comprises peroxide. The peroxide compound may comprise from about 2% to about 30% by weight of the composition. More particularly, the peroxide comprises from about 3% to about 15% by weight of the composition. A typical peroxide concentration in the composition is generally from about 2% to about 7% by weight for home use products, and from about 15% to about 20% by weight for dental professional use.

Thickening or gelling agents used in dentifrice compositions may include nonionic polyoxyethylene polyoxypropylene block copolymers. Illustrative of polyoxyethylene polyoxypropylene block copolymers useful in the practice include block copolymers having the formula HO(C₂H₄O)_(b)(C₃H₆O₆)_(a)(C₂H₄O)_(b)H wherein a is an integer such that the hydrophobic base represented by (C₃H₆O₆) has a molecular weight of about 2,750 Da to 4000 Da, b is an integer such that the hydrophilic portion (moiety) represented by (C₂H₄O) constitutes from about 70% to about 80% by weight of the copolymer. Block copolymers of this composition are available commercially under the trademark Pluronic® F type.

Pluronic® F127 has a molecular weight of 4,000 Da and contains 70% of the hydrophilic polyoxyethylene moiety.

Also suitable as a thickening agent is lightly- to moderately-crosslinked PVP, described in international application PCT/US11/30642.

The thickening agents may be present in an amount from about 15% to about 50% by weight, particularly from about 25% to about 45% by weight of the composition.

Surfactants may also be included in the oral care compositions of the invention, where they may serve in solubilizing, dispersing, emulsifying and/or reducing the surface tension of the teeth in order to increase the contact between the tooth and the peroxide. The compositions may also comprise surfactants, also commonly referred to as sudsing agents. Suitable surfactants are those which are reasonably stable and foam throughout a wide pH range. Surfactants may be chosen from anionic, nonionic, amphoteric, zwitterionic, or cationic surfactants, or blends thereof.

Anionic surfactants useful herein include the water-soluble salts of alkyl sulfates having from 8 to 20 carbon atoms in the alkyl radical (e.g., sodium alkyl sulfate) and the water-soluble salts of sulfonated monoglycerides of fatty acids having from 8 to 20 carbon atoms. Sodium lauryl sulfate (SLS) and sodium coconut monoglyceride sulfonates are non-limiting examples of anionic surfactants of this type. Many suitable anionic surfactants are disclosed in U.S. Pat. No. 3,959,458. The compositions may comprise an anionic surfactant in an amount from about 0.025% to about 9% by weight, particularly from about 0.05% to about 5% by weight, and more particularly from about 0.1% to about 1% by weight of the composition.

Non-limiting examples of suitable anionic surfactants include: sarcosinates, taurates, isethionates, sodium lauryl sulfoacetate, sodium laureth carboxylate, and sodium dodecyl benzenesulfonate. Also suitable are alkali metal or ammonium salts of surfactants such as the sodium and potassium salts of the following: lauroyl sarcosinate, myristoyl sarcosinate, palmitoyl sarcosinate, stearoyl sarcosinate, and oleoyl sarcosinate. The sarcosinate surfactant may be present in the compositions from about 0.1% to about 2.5%, particularly from about 0.5% to about 2.0% by weight of the total composition.

Also suitable are flavor chemicals that may undergo some oxidation or degradation without resulting in a significant change in the flavor character or profile. The flavor chemicals, including menthol, may be provided as single or purified chemicals rather than supplied in the composition by addition of natural oils or extracts such as peppermint, spearmint, or wintergreen oils as these sources may contain other components that are relatively unstable and may degrade in the presence of peroxide. Flavoring agents are generally used in the compositions at levels of from about 0.001% to about 5% by weight of the composition.

The flavor system may typically include sweetening agent(s). Sweeteners include compounds of natural and artificial origin.

Water-soluble sweeteners derived from naturally occurring water-soluble sweeteners, such as a chlorinated derivative of ordinary sugar (sucrose), known, for example, under the product description of sucralose as well as protein based sweeteners such as thaumatoccous danielli (Thaumatin I and II) may be used. The compositions may contain sweetener(s) in an amount from about 0.1% to about 10% by weight, in particular from about 0.1% to about 1% by weight of the composition.

In addition, the flavor system may include salivating agents, warming agents, and numbing agents. These agents are present in the compositions in an amount from about 0.001% to about 10% by weight, particularly from about 0.1% to about 1% by weight of the composition.

Oral care compositions may comprise chelating agent(s).

The chelating agents may include metal solubilizing agents and metal precipitating agents. The metal solubilizing agents include a condensed pyrophosphate compound. For purposes of this invention “condensed phosphate” relates to an inorganic phosphate composition containing two or more phosphate species in a linear or cyclic pyrophosphate form. The condensed phosphate may be sodium pyrophosphate, but may also include tripolyphosphate, hexametaphosphate, cyclic condensed phosphate or other similar phosphates well known in the field. The blend may also include an organic chelating agent. The term “organic phosphate” includes phosphonic acid, di and tri phosphonoc acid compound or its salts. An example of phosphonic acid is 1-hydroxyethylidene-1,1-diphosphonic acid that is sold under the trade name of Dequest®. The blend may also include a metal precipitating chelating agent. The term “metal precipitating chelating agent” is an agent that binds to metals and causes the metal to precipitate and includes halogens such as fluoride. The chelating agents are incorporated in the oral care compositions of the invention in an amount from about 0.1% to about 8.0% by weight, and particularly from about 0.5% to about 3.0% by weight of the composition, in a ratio of about 3:1:1 w/w organic chelating agent: condensed phosphate chelating agent: metal precipitating agent.

Another optional ingredient that may be used in oral care compositions is a humectant. For example, a humectant may be added to keep toothpaste compositions from hardening upon exposure to air, to give compositions a moist feel to the mouth, and, for particular humectants, to impart desirable sweetness of flavor to toothpaste compositions. The humectant, on a pure humectant basis, is generally present from about 0% to about 70%, particularly from about 5% to about 25% by weight of the composition.

Non-limiting examples of suitable humectants include: edible polyhydric alcohols such as glycerin, sorbitol, xylitol, butylene glycol, polyethylene glycol, propylene glycol, trimethyl glycine, and blends thereof.

Oral care compositions may comprise one or more denture adhesives.

Synthetic materials presently dominate the denture adhesive market. Such materials may consist of mixtures of the salts of short-acting polymers (e.g., carboxymethylcellulose or “CMC”) and long-acting polymers (e.g., poly[vinyl methyl ether maleate], or “Gantrez” and its salts). Polyvinylpyrrolidone (povidone) may also be used.

Other components of denture adhesive products impart particular physical attributes to the formulations. Petrolatum, mineral oil, and polyethylene oxide may be included in creams to bind the materials and to make their placement easier. Silicon dioxide and calcium stearate may be used in powders to minimize clumping. Menthol and peppermint oils may be used for flavoring, red dye for color, and sodium borate and methyl- or poly-paraben as preservatives.

It is also contemplated that the composition ingredients may be formulated in a single container, or the ingredients may be formulated in-part in two or more distinct containers of the same or different type, the contents of which may require mixing prior to use.

The UV-absorbing polymers according to the invention may be prepared according to the examples set out below. The examples are presented for purposes of demonstrating, but not limiting, the preparation of the compounds, polymers, and non-homopolymers according to the invention.

Example 152: Poly(IB/MA) Grafted with DIOPAT, Dimethylaminopropylamine; Full Imide Form

A 1-L, 4-neck round-bottom flask was charged with ethanol (250 mL), 37.5 g 2,4-bis-(2,4-dihydroxyphenyl)-6-(4-methoxyphenyl)-s-triazine (DIOPAT) and 85.0 g (0.657 mol) of dimethylaminopropylamine, and a yellow-gold slurry formed with mixing. A KOH/water solution was then added that formed a loose light orange mixture after one hour of mixing. During this time, the reaction temperature increased from 25 to 30° C. A doughy sample was collected and submitted for ₁HNMR analysis. The balance of the product was collected from the flask and charged to a PARR reactor. The PARR heating schedule was programmed to ramp from 25° C. to 100° C. in 30 min. Temperature was held at 100° C. for 3 hours, ramped to 145° C. and held at 145° C. for 4 hours. Finally, the reactor was cooled to 50° C. and maintained over night. The next morning, the product was discharged as 200 g total solids.
